1. A method for predicting GNSS satellite trajectory extension data in a mobile apparatus, said method comprising steps of:

  • obtaining at least one satellite navigation message for a satellite;

    determining a propagating condition according to the obtained satellite navigation message;

    estimating a plurality of parameters of a satellite trajectory prediction model according to the propagating condition; and

    propagating a set of satellite trajectory extension data by using the estimated satellite trajectory prediction model.
